244 REPORT UPON COTTON INSECTS. 



No. 1 in the cut is an end view of the machine ; No. 2 is a plane view, 

 and Xo. 3 is a side view of the same. 



A A' designate, respectively, the front and rear bars of the frame, connected to- 

 gether on each side by means of a platform, C, upon which are to be placed oil-cans, 

 B, or other convenient vessels for the reception of the destroying compounds. These 

 vessels are removably secured thereto in any suitable manner, and their outer lateral 

 edges are each provided with a distributing stop-cock, D, having a crescent-shaped 

 perforated nozzle-piece, d, by means of which the liquid poison will be shed over a 

 wide space. The front bar A has an angular notch, E, cnt into its lower edge, near 

 the apex of which, and one each side thereof, perforations, e, are made, by means of 

 which it is secured to the pommel of the saddle. It is also provided with perforations, 

 e 7 , upon its lower edge, by means of which it is laterally stayed by a rope passing 

 thence to the girth-rings on each side of the saddle. The rear bar A' is in like man- 

 ner notched, as shown in Fig. 2, and is provided with a slot, /, at the apex of its 

 notch, by means of which it is strapped to the cantle of a saddle, and with perfora- 

 tions, f, along its lower edge, serving as a means of attachment for a rope, passing 

 thence to the girth-rings on each side. 



It will be seen from the above description that the frame is firmly attached both to 

 the pommel and cantle of the saddle, and that it is braced and steadied to resist dis- 

 placement by ropes or straps leading from the perforations d and f upon the front 

 and rear bars of the frame, respectively, to the girth-rings on each side of the saddle, 

 constituting a simple, convenient, and etfectual attachment for the purpose of pre- 

 venting any displacement. The notches of the front and rear bars A' A are intended 

 to be straddled over that portion of the pad-frame of a saddle which projects in front 

 of the pommel thereof, and extends in rear of the cantlo, the rider being seated be- 

 tween the two, with a poison-receptacle on each side, with their stop-cocks within 

 easy reach of his hand. He can thus accurately regulate the flow of poison accord- 

 ing to the amount required to effect the purpose, the movement of the horse serving 

 materially to assist the distribution. 



Hon. John W. Johnson, of Columbus, Tex., has patented a machine 

 for distributing liquid poisons upon cotton plants. This machine has 

 been used to a considerable extent in Texas; it is represented in Fig. 54. 



The following description will explain its workings : 



This invention relates to certain improvements on that for which I filed an applica- 

 tion for letters patent on the 22d day of September, 1873; and the invention consists 

 in a tank provided with a double-acting force-pump, communicating with a pipe and 

 branches similar to those described in my application aforesaid, the pump being con- 

 nected by a pitman with one of the wheels upon which the tank is supported, 

 whereby the pump is operated automatically as the apparatus is drawn along, the 

 wheels upon which the apparatus is supported being much smaller in diameter than 

 ordinary cart or wagon wheels, and attached to the tank by means of vertical bars, 

 whereby the apparatus is enabled to pass over the rows of cotton-plants without in- 

 juring them, while at the same time the dimensions of the wheels are such as to give 

 the required number of strokes to the pump-lover necessary to the producing of a con- 

 stant and full volume of spray from the pipes. 



In the accompanying drawing, Fig. 1 is a side view of my invention ; Fig. 2 is a 

 top view of the same ; Fig. 3 is a sectional view of one of the branch pipes. 



A represents the tank containing the liquid compound described in my application 

 aforesaid. Instead of placing it upon an ordinary cart or wagon and working the pump 

 by hand, I attah the tank to a platform or cart-bed, B, provided with two wheels, C. 

 These wheels are much smaller than ordinary cart-wheels, being about twenty or twen- 

 ty four inches in diameter, in order to give the required number of revolutions neces- 

 sary to the successful operation of the pump. In order to place the cart-bod at such
